DUST-BLOWING ATTACHMENT FOR BROOMS, BRUSHES, AND THE LIKE.

Specification of Letters Patent.

Application filed April 8, 1909. Serial No. 488,679.

To all whom it may concern:

Be it known that I, FRANK G. DAVIS, citizen of the United States,residing at Tucson, in the county of Iima and Territory of Arizona, haveinvented certain new and useful Improvements in Dust-Blowing Attachmentsfor Brooms, Brushes, and the Like; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to an air blowing attachment for brooms andsweepers.

The object of this invention is to provide a simple and efficient devicefor use in connection with brooms and sweepers to pro duce an air jetfor blowing the dust out of corners and other places inaccessible to abroom.

With this and other objects in view, the invention consists of certainfeatures of construction, combination and arrangement of parts as willbe more fully described and particularly pointed out in the appendedclaims.

In the accompanying drawings: Figure 1 is a front elevation of a broomequipped with this improved attachment; and, Flg. 2 is a similar view onan enlarged scale' with the handle shown in longitudinal verticalsection.

In the embodiment illustrated a broom 1, is shown having a pump cylinder2, forming a ortion, of the handle and which is provi ed at its lowerend with a metal casting 3, which is preferably detachably connectedwith the head 4, of the broom by means of an internally screw threadedshank 5, which is screwed into a threaded socket 6, formed in the lowerface of said casting. This casting is also provided with two laterallyextending valved channels 7, and 8, communicating with the interior ofthe cylinder 2, the channel 7, being provided with an inlet valve 7,opening to the atmosphere and the channel 8, communicates at its outerend with a tube 9, hereinafter described and is provided with an outletvalve 10.

The upper end of the cylinder 2, is closed by a casting 11 constructedsimilarly to the casting 3, but arranged in reverse position having ascrew threaded socket 12, formed in its upper face for the reception ofthe lower end of the upper portion'of the hollow broom handle 13. Thiscasting 11, is also provided with an inlet channel 14, having an inletvalve 15, arranged at its outer end with an outlet channel 16,communicating with the upper end of the tube 9, and provided with anoutlet valve 17. A piston rod 18, extends through a central aperture inthe metal plug 19, which closes the outer end of the handle member 13,and throu h an aperture in the casting 11, and extenfs into the cylinder2 and is provided at its lower end with a piston 20, operable in saidcylinder for compressing the air to be sup lied to the tube 9. This rod18, is preferab y provided at its outer end with a wooden handle 21, forthe convenient manipulation of the piston for compressing the air in thecylinder 2.

T e tube 9, is preferably made of metal and is soldered to the exteriorof the cylinder 2, and is connected at its upper end with the outletchannel 16, of the casting 11 by means of a coupling 22. This couplmgpermits the unscrewing of the upper pump castin from the cylinder tofacilitate cleaning 0 the parts.

A. metal tube 23, extends through the straw head of the broom and isheld by friction rigidly in position and may be moved upwar ly toprovide for wearing away of the broom straws. The lower end of this tube23, is provided with a small nozzle 24, which preferably extendsoutwardly at an angle to the broom head and is adapted to insure reaterpressure with light pumpin A ru ber hose 25, is preferably used orconnecting the lower end of the metal tube 9, with the upper end of thetube 23, to provide for any variation in different brooms and to avoidthe use of expensive screw couplings.

When it is desired to extract dust from the corners of furniture, roomsor other places air is compressed within the cylinder 2, by manipulatingthe piston 20, and is forced out through the outlet valves 10, and 17,into the tube 9, and passes downwardly therethrough and is discharged ina jet like stream through the nozzle 24, onto the arti cle to be dusted.

It is evident that the broom may be used for ordinary sweepin pur osesand the air blowin attachment roug t into use only when desired. Thisattachment may also be used if desired for dusting picture moldings,picture frames or any kind of bric- Patented Apr. 5, 1910.

a-brac dis osed-beyond the rea'ch of the dust cloth sim y by raising theend of the broom to the esired height and operating the piston as abovedescribed.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operationof the invention will be readilyunderstood without requiring a more extended explanation.

Various 0 anges in" the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claims.

I claim as my invention:

1. A hollow broom handle having means for detachable engagement with abroom head, said handle having a valved inlet and outlet, a pistonoperable in said handle, and a tube connected at one end with saidoutlet and provided at its other end with a nozzle adapted to penetratesaid head. and dis charged at one side thereof;

2. The combination with a broom head having a screw threaded member, ofa hollow handle having a casting secured in its lower end and providedwith a threaded member for engagement with said screwthreaded broom headmember, said casting having laterally extending valved channelscommunicating with the interior of the handle, a tube connected with oneof said channels and extendin into the head of the broom, the free en ofsaid tube being bent outwardly and extending through the side of saidhead. I

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
